Paper Title:
The Research of Dynamic Properties on the Roof in Ancient Timber Buildings
  Abstract

Take the roof of the palace timber structure as the study objection, according to the requirements of the Ying-tsao fa-shih, it establishes the model. Through the analysis of the dynamic properties with ANSYS finite element software and shaking table test, it gets the structural dynamic properties and its maximal response under different conditions, and abstains the seismic amplification coefficient of the beams layer and the whole structure, compares the results reached by shaking table test with the numerical simulation. Research shows that the nature frequency of the model is 1.486 Hz; the roof’s nature frequency is much bigger than that of the whole structure; with the increase of earthquake and the height of model, the maximal displacement value of beam layer gradually increases; the shock absorption effect of semi-rigid Sun-Mao connection in major earthquake (400gal) is better than that in moderate earthquake (220gal)and minor earthquake (110gal); the seismic amplification coefficient value between layers lies in 1, that between roof and arch shop lies in 0.9 or so.
